Viewing the PL5 user guide (PDF document) and searching for the word FilmPack will highlight descriptions of the added functions.

I tend to apply them at around 5-20% intensity. Warm and Cool change the overall color temperature in ways I like. I also use Mauve and the more subtle Orange filters to adjust the look of landscapes so that colors are more in balance/complementary.
